Staying in touch with friends has resulted in carpal tunnel syndrome for one Chicago-area teenager.  The local newspaper is reporting that Annie Levitz developed the affliction after sending approximately one-hundred text messages a day.  The 16-year-old Lincolnshire Stevenson High School student says she first started experiencing numbness in her hands.  A doctor eventually diagnosed Levitz with carpal tunnel, requiring her to wear braces on her arms whenever she is in pain.  Levitz, who may need surgery on both of her wrists, says she has since reduced her text messages to about 20 or 30 a day.  She states, quote, "Never think (carpal tunnel) can't happen to you, because it can."
